Summary

Trojan:Win32/Liften is a trojan that is used to stop affected users from downloading security updates. It is downloaded by Trojan:Win32/FakeXPA - a family of programs that claims to scan for malware and displays fake warnings of “malicious programs and viruses”. They then inform the user that they need to pay money to register the software in order to remove these non-existent threats.
